Researchers in Japan have confirmed microplastics are present in clouds, where they are likely affecting the climate in ways that aren't yet fully understood.
Probably a piece of microplastic. Not trying to be facetious. Microplastic already refers to a size of a piece of plastic as opposed to the material in general. Sort of like how gold is a material and a gold nugget is a piece of gold. As for how big this is what Wikipedia says the NOAA says.
Microplastics are fragments of any type of plastic less than 5 mm (0.20 in) in length, according to the U.S. National Oceanic and Atmospheric Administration (NOAA)[1][2] and the European Chemicals Agency.[3] They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and industrial processes.[4]
So would that mean it is assumed that microplastics are spherical and the length refers to the diameter? So that we could calculate percent concentration by using the volumes.
